Investigating the movement ecology of two closely related kestrel species with contrasting behaviours
(2024-05-23)
En esta tesis doctoral empleamos dispositivos GPS y acelerómetros triaxiales para estudiar la ecología del movimiento de dos especies de cernícalo estrechamente emparentadas: el cernícalo primilla y el cernícalo vulgar. ...

Linking Self-Incompatibility, Dichogamy, and Flowering Synchrony in Two Euphorbia Species: Alternative Mechanisms for Avoiding Self-Fertilization?
(Library of Science, 2011)
Background: Plant species have several mechanisms to avoid selfing such as dichogamy or a self-incompatibility response. Dichogamy in a single flower may reduce autogamy but, to avoid geitonogamy, plants must show ...

Pollen flow in fragmented populations of myrtus communis and pistacia lentiscus: the importance of mating, pollination systems and the landscape context.
(2017-09)
Over the last century, habitat loss and fragmentation have been the main components of current anthropogenic global change and the greatest threats to the global biodiversity. The scientific community has shown a growing ...

Global Urban Environmental Change Drives Adaptation in White Clover
(American Association for the Advancement of Science, 2022)
Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 ...

The Pyrenees as a cradle of plant diversity: phylogeny, phylogeography and niche modeling of Saxifraga longifolia
(Wiley, 2023-03)
The current distribution of most species results from ecological niche, past distribution, and migrations during glacial–interglacial periods and in situ evolution. Here, we disentangle the colonization history of Saxifraga ...

The turnover of plant-frugivore interactions along plant range expansion: Consequences for natural colonization processes
(The Royal Society, 2023-05-31)
Plant-animal mutualisms such as seed dispersal are key interactions for sustaining plant range shifts. It remains elusive whether the organization of interactions with seed dispersers is reconfigured along the expansion ...

Unpacking the recruitment potential of seeds in reconstructed soils and varying rainfall patterns
(CSIRO Publishing, 2023-06-05)
Context: Seeding is common practice for ecological restoration, but establishment rates can be low. For seeds to successfully establish they must transition through early life stages of germination, emergence, and (initial) ...
